Eagle Dock Floats Eagle floats are a one-piece rotationally molded part, which eliminates seams than could result in separation and leakage. The .150" nominal thick shell is made of extra strong virgin polyethylene containing ultraviolet inhibitors. This tough shell helps prevent damage from oil, gas, and marine organisms. Each float has a solid, foam-filled, expanded polystyrene core that is produced using precision computer-controlled technology. Eagle dock floats have a flat top with molded-in mounting slots for easy attachment to any dock framework; whether wood, steel or aluminum. Floating docks built with Eagle dock floats will provide long lasting and carefree encapsulated flotation, resulting in long-range savings for recreational docks and complex marinas.
